MORRIS SCHOENFELD, 0F RORSCHACH, SWITZERLAND.

EMBROIDERING-MACHINE.

To all whom it may concern:

Be it known that I, MORRIS SCHOENEELD, a citizen of t-he United States, and a resident of Rorschach, in the Canton of St. Gall, I Switzerland, have invented certain new and useful Improvements in Embroidering-Machinos, of which the following is a specification.

The present invention relates to the construction of embroidering machines wherein several hundred needles simultaneously operate to produce embroidery upon a fabric and the object thereof is to completely revolutionize the construct-ion of such machines.

The present invention not only relates to thel struc-tural features of the machine, but also to certain mechanisms, while other cases being filed by me embody mechanisms especially adapted for the present structures.

It is my object to entirely improve the structure of the machine, but to preserve the present arrangement, in so far as the arrangement of the needles and other mechanisms on one side of the fabric and the shuttles on the other, is concerned.

The principal features of the present case are in the arrangement of the framework. Heretofore the framework of an embroidering machine was constructed generally of four heavy cast iron horizontal beams which were rigidly attached at both ends to vertical frame posts or standards. Of these four beams two were invariably arranged in front and adapted to carry the needle and other devices necessary o-n the front of the work to be embroidered; while the other two beams were on the rear side and were equipped with the mechanism for the operation of the shuttles and such other mechanism as operated from the rear of the fabric. From this type which has hitherto been generally used, the present invention is distinguished particularly by the fact that the numerous working mechanisms are not carried primarily by heavy longitudinal beams but by a number of upright posts, or frames, arranged at comparatively short transverse of the longitudinal direction of the machine. The groups of embroidering tools and their mechanisms may be secured either directly or indirectly to these upright frame sections.

The objects of such novel arrangement are manifold. A clear view of the fabric is afforded to the operator through the machine Specification of Letters Patent.

frame, so that the operator and attendants in charge of the machine have a less obstructed View of the embroidery surface whereas hitherto a large portionof the embroidery surface has been covered by the heavy frame beams.

Another object is to make it possible to provide more than two rows or series of ncedles, one above the other. In the accompanying drawings a machine is shown havmg siX rows of needles and sewing implements. Hitherto this increase has been impossible for the reason that for each row of needles special beams had to be provided, which, owing to their great length and the weight carried by them between their points of support were comparatively large. If more than two beams were arranged one above the other hardly anything could be seen of the embroidery surface, and the manual manipulation of the parts between the beams for the purpose of arranging the various devices and threads would be impossible.

Another important advantage of my invention is that the rowsof needles and the associated mechanisms in the front of the machine and the shuttles or other mechanisms in the rear can be adjusted in vertical direction, whereby the sewing can be performed at various positions upon the fabric. That is the rapport rows can be made more or less remote from one another. Hitherto this adjustment has been impossible because the positions of the various groups of tools was necessarily a determined factor owing to the position of the heavy longitudinal beams referred to and also because of the difficulty of adjusting such a cumbersome arrangement of mechanism. As the longitudinal supporting beams formed a constituent part of the machine frame, it was impossible to change their connections with the vertical port-ions of the frame, to secure vertical adjustment of the mechanisms.

ln the present invention the various mechanisms are supported by vertical frame members, as distinguished from longitudinal frame elements which are themselves supported at the ends of the machine by frame members. The present invention embodies a number of features which may be used in a single machine as herein shown, but some of the features may be advantageously used separate from the others.

The present invention does not necessarily eliminate longitudinal frame members, but where they are here used they are for connecting the various vertical trame members to provide a rigid whole, rather than to directly support the working mechanisms, and they are positioned where they will not obstruct the embroidery surt'ace.

Various other advantages will be apparent from the detailed description hereinat'ter.

In the drawings forming a part of this application, Figure 1 is a cross section through the trame ot an en'ibroidering machine showing my invention in one ot its forms. F ig. 2 is a side elevation oit one end of the machine trame, with the mechanisms omitted for simplicity in illustration, Fig. S is a cross section of a trame showing a Yariation in the construction, wherein the upright trame element is in the form ot a single casting. Fig. t is a side elevation ot one end of the trame with the form ont construction the same as in Fig. 3, Fig. 5 is a cross section of a frame embodying still another form ot construction, Fig. 6 is a side elevation et one end ot the trame shown in Fig. Fig. 7 is a cross section of the frame, showing how the operating elements for producing the embroidery may either hare permanent positions upon the upright frame members or may be adjustable in vertical relation, the latter embodying my invention more fully, Fig. 8 is a side elevation of one end ot the trame illustrating several ways in which the operating` elements may be vertically adjusted upon a frame of the torni shown in Fig. 7, Fig. 9 is a cross section ot a frame embodying a still (litter-ent modification in structural de` tails and in which additional features of my invention are shown, Fig. 10 is a view similar to Fig. 9, showing my invention carried to a higher point of development, wherein the embroidering elements are vertically adjustable on the trame, Fig. 11 is a detail view showing certain operating mechanism, Fig. 1Q is an elevation of a modiied torni of tension device, Fig. 13 is a cross section ot the rear of the vertical frame of Fig. 10, showing one way o1 vertically adjusting the shuttle track or guide, Fig. 111 is a horizontal section showing the location of parts of the mechanism ot Fig. 10, and F 15 and 15 are diagrammatic views illustrating several ways ot' distributing the sewing mechanisms to give a clear view ot the embroidery surface.

In the .several views of the drawings I have omitted much ot' the mechanism which may be of the well known construction, for the purpose of simplifying the present case, such as the fabric frame and its operating mechanism.

In the present invention the structural frame features form an important part and the same may be combined with the additional. mechanical features herein shown, but these trame features may be advair tageously used with other mechanism without departing from the broad spirit of my invention, though I prefer to employ either the particular meclianism herein shown or other mechanism conforming to the broad spirit ot my invention.

In the present invention the devices or mechanisms tor producing embroidery upon a fabric are shown as supported directly or indirectly upon upright trame members. These mechanisms may extend the length of the trame of the machine and be supported at various places along their length by the upright traine members; or they may be connected to long rails or longitudinal connections which are themselves supported throughout their length by the vertical trame members, but theserails, owing to the small. load which they are required to support between any of their vertical points of support by the upright trame members cannot be considered as carriers or beams in the same sense the beams ot tormer constructions. On the other hand the operating elements may be :formed in groups, the several groups being independently arranged betwecn the various upright trame members and operated from a common .source oit operation to make them operate in unison. Nhere long rails are used to support mechanisms they are ot considerably less depth than the carrying beams ot former constructions whereby a clear view et the embroidery surface may be had by the operator or attendants during the embroidering operation, and this is possible because ot the upright trame members which take no the load and shocks exerted by th vvarious operating parts. INhere the longitudinal rails are not interposed, the upright trame members likewise take u p the weight and shocks. In a broad sense the result produced in either case is similar, because the upright trame members carry the load at Vvarious points throughout the length ol. the machine and receive the shocks. IV here in `former machines the operating elements are directly supported upon longitudinal beams and the shocks transmitted by them to the extreme ends ot the machine the vibrations are intensitied.

In the form ot frame shown in Figs. 1 and 2 I have provided upright end frame elements 1, only one ot which is shown, it being understood that the same is duplicated at the opposite end oit the machine; and between these upright trame members I have provided at various, and preferably regular, intervals upright frame members Q upon which the weight and shocks of the operating elements are adapted to come. In the drawings only two ot these intermediate frame members are shown, but it is understood that these are multiplied to carry the length of the machine to any desired eX: tent, which may be greater than former machines, and which may extend as far as power can be uniformly supplied to the operating elements. These upright frame members and the end frame members may be connected in various ways to form a rigid whole of the frame, but the elements for connecting these various members are so disposed as not to interfere with the clear view of the embroidery surface. In the form now considered I have constructed the upright frame members of a plurality of sections 3 and 4 preferably ofv thin metallic plates, easily cast or otherwise formed, having flanges 10 at their base which rest upon the floor which supports the machine; and at the top they are arched toward each other at 11 to form an intermediate space in which the longitudinal tambour frame and fabric are adapted to operate and wherein the embroidering elements are partly disposed. The arch portions 11 I have provided with lateral abutting flanges 12 by which the members 3 and 4 firmly abut against each other. In the present showing the longitudinal rigid connecting means referred to consists of a series of short tubes 8 and.9 abutting against the opposing sides of the various upright frame members, near the base, and these several tubes are connectedA with each other by connecting bars 13 (see Fig. 2) of reduced diameter, which pass through apertures in the frame members and connect the ends of the adjoining tubes. At the top of the frame I have provided a longitudinal beam 5 which is preferably secured by the bolts 7 to the iianges 6 of the several upright frame members whereby a rigid frame is formed. For this longitudinal beam 5 various forms of commercial iron or steel may be advantageously used, to make the construction simple, strong and inegipensive.

The frame constructed as above forms a rigid whole, having a longitudinal space for the tambour frame and its fabric which tambour frame and its operating mechanism may be of any well known co-nst-ruction but which is not made a part of the present case. In this showing I have illustrated how the needle bars 14 may be arranged one above the other in greater numbers than heretofore, in this form as many as siX needle bars being shown arranged one above the other; and these bars have laterally extending shafts 15, arranged at various places therealong which move laterally of the machine in guiding sockets or lugs 16 formed on the various upright frame members; and the needle bars preferably terminate within the longitudinal limits of the machine as defined by the end members 1. It will be seen that this arrangement permits the needle bars to be reciprocated toward and from the fabric to cause the needles to pro-duce the necessary stitching thereon. r1`he shuttle tracks 17 which guide the shuttles are shown secured to the rear portions 3 of the upright frame members by angle plates 18, opposite the several needle bars, whereby the shuttles may be operated in conjunction with the needles of the several needle bars.

Before passing to the embroidering mech-' anism I will describe some of the modified forms in which my invention, in so far as the frame construction is concerned may be embodied.

In Figs. 3 and 4 the upright frame members 19 are formed each of one component piece, and these are all secured to a common base plate 21, and at the top they are connected to each other by the arched spacing beams 20, the ends of which abut against each other and are bolted to the several frame members to produce a rigid frame structure. In this showing there are provided T bars 22, bolted between the opposing frame members, which support the several needle bars 23 at various points throughout their length instead of by means of the integral lugs o-n the frame members as previously described. These bars 22 may be small enough to prevent any material interference with a clear view of the embroidery surface and they are not to be considered as the equivalentI of the longitudinal beams of former constructions.

In Figs. 5 and 6 the upright frame meml bers are composed of a pair of separately formed plates 24, 25, for the front and rear which are united at the top by a tie plate 26, by means of the bolts 27 and they are secured at their base to a base plate 21, common to the several frame members. In this construction the needle bars and other mechanisms as desired are supported upon tubular connections 28 which engage between the sockets 29 on the opposing sides of the several frame members. These tubes not only tend to support the operating parts but they also serve as spacers for the upright frame members. The upper portions of the various frame members are longitudinally tied by means of a tie rod 29a inside a tube 30, the nuts 81 on the ends of the tie rod and outside of the frame ends serving to clamp the parts together.

In Figs. 7 and 8 I have shown further steps in my invention the purpose here being to illustrate the use of my. frame construction with the various mechanisms having either a fixed relation upon the frame or adjustable, the latter being a fuller embodimentl of my invention. The frame construction I have here shown is similar to that in Figs. 1 and 2 and the parts thereof are similarly numbered. 'Ihe upper rows of needle bars in Fig. 7 correspond with the showing in Fig. 1 while the two lower rows show how the needle bars (and other mechanism) may be vertically adjusted for the purpose of forming the rows of embroidery at varying distances apart on thc fabric 32. These alterations are desirable where it is necessary to operate the machines for various kinds of work, such as handkerchiefs, neckwear etc. The needle and related mechanisms may be adjusted in a vertical direction to place the 'various rapport rows of embroidery at equal distances, or the various rows may be placed with varying distances between them to suit the requireinents. rFhe four top rows of needle bars in Fig. 7 and the third row of Fig. 8 have an unalterable position, while the remaining rows are made adjustable in several different ways. In the fifth row the angle metal bars 33 are secured between the various upright frame members by means of bolts 34e which engage in the apertures in the depending brackets 37 of the bars 33 and in slots 35 of the uprights and the upward ears 36 form the sockets in which the shafts 15 of the needle bars are guided. rlhe position of the needle bar may be vertically adjusted by means of this bolt and slot connection of the supporting bars 33 with the frame members. In the sixth row the form of construction is varied by providing round tubes 38 to which the sockets 39 for the needle bar shafts are secured.

In the top row of AFig. 8 the adjustment is made by means of the brackets or sockets L,t0 which are adjustably connected directly to the frame. The bolt s1 passing through an ear t2 on the frame is threaded through tht` bracket Ll0 and. by turning the bolt the vertical position of the needle bars are adjusted. The set screw e3 will prevent any change in the adjustment during the operation of the machine.

In the second row the brackets are secured to the frame by a bolt ftd which engages in a slot 15 in the frame whereby vertical adjustment may be made. In the fourth row this is slightly varied by a plurality of holes which take the place ot' the slots of the second row. These show how the manner of adjustment may bc varied under the broad scope of my invention and many other means of adjustmentmay be conceived.

In Figs. 9 and 10 I have carried the illustration of my invention further by showing the application of my improved embroidering mechanism to a machine ofmy improved type and in doing so I have illust-rated a modified form of frame construction. In these views I have shown the embroidering devices with a vertical fixed position, and also having means for vertical adjustment., the latter embodying more fully the features of my invention. In this construction I have shown a modified form of frame though itis understood that the mechanism is applicable to the previously described forms and others. I have employed quite large upright end sections 47 and these support the longitudinal beams 18, 4), 50 and 51 between them, which beams may be of commercial forms of angle metal. Between these beams I have arranged, in pairs, the intermediate upright frame members, which I have shown built up of commercial forms of metal. The fronthalf 52 of the sections are composed of riveted metal bars, and are disposed between the beams 48 and 49, while the rear half is composed of an I beam disposed between the beams 50 and 51. This form embodies the broad principles of construction "arried through the entire case and makes the multiplication of needle mechae nism possible.

In Fig. 9 the mechanisms are shown with a fixed vertical position but embodying the broad principles of distribution of power Ato the mechanisms and the mechanisms themselves. The mechanism here shown as an example is the needle mechanism on the front of the machine, it being understood that the principles involved in this may be employed for other tools. It may be first stated that the longitudinal shuttle tracks 17 are suitably connected. along their length to the rear elements 523 in such positions as to coperate with the mechanisms on the front of the machine. On the front side of the fabric 32 I have arranged the various needle bars, tension, spool racks, take up etc., in rows, one set above the other, and disposed so that the support thereof is taken up by the frame men'ibers, and they are operated from a common source of power. rIhe shaft 54 is the drive shaft for distributing the operating force throughoutthe machine for the various mechanisms and from this shaft the power is transmitted to upright driving members preferably by means of cams distributed along the shaft, having peripheries formed according to the requirements of the various elements operated thereby.

In Fig. 9 there are castings or b ackets 56 arranged on the several upright frames to provide supporting means for the needle bars etc. rIhe needle bars 1% are disposed loiigitudinally of the machine, in front of the fabric, and preferably have lateral shafts 15 which engage in sockets forming a part of the brackets 56, whereby the needle bars may be moved to and from the fabric to cause the many needles to stitch the fabric. These shafts 15 are fulcrumed to links 58 which in turn are fulcrumed to the bellcrank lever 59. The link 5S is suitably fulcrumed to the frame to rock preferably vertically, whereby the power necessary to operate the needle bar is derived from the cam on the main shaft 54 by means of an upright pitman 60 having a roller which is held in contact \with the periphery of one of the cams 55 by means of a spring 61. The various pitmen are connected with the various bellcrank levers 59 of each tier, causing the various needle bars to move in unisonand I prefer to provide a driving arrangement such as described, on each of the upright frame members, whereby t-he needle bars will be all driven uniformly throughout their length. I have also secured to the brackets 56 the bobbin holders 61a, for holding the bobbins of thread, preferably immediately below the needle bars and from these bobbins the threads pass around the tension or let olf rolls 62, t-he axles 63 o-f which are j ournaled in t-he brackets 56, preferably on a longitudinal line with the needle bar to obstruct as little as possible the view of the embroidery surface. From the tension roller the threads pass over the take up bars 64, which rock on the arms 65 fulcrumed by shafts 66 to the brackets 56. Extending forward from the shaft 66 is an arm 67 which connects with a pitman 68. The latter is operated fro-m the shaft 54 by means of one of the cams 55 in a similar way to the pitman 60 but the extent and time of movement is such as to give a proper movement to'the take up bars 64.

It will be apparent that the mechanism is properly and uniformly driven throughout and because of the disposition of the parts it is possible to view the embroidery surface while employing a larger number of needle bars arranged one above the other.

In Figs. 10, 13, and 14 the mechanisms are shown vertically adjustable. Instead of the brackets 56 having fixed positions they are adjustably secured by means of the bolts 69 which engage in the slots 70 by which the brackets may be adjusted to change the relative positions of the embroidering mechanisms. This necessitates an adjustment in the operating parts and I therefore connect the bellcrank levers 59 to the pitman 60, by means of bolts 72 engaging in slots 71, whereby the connections may be adjusted; and the lever 67 is similarly connected to the pitman 68 by means of the bolt 73 engaging through the slot 74.

In Fig. 10 I have also shown a detent mechanism which is adapted to press the detent fingers upon the fabric, near the needles, and against the shuttle tracks. The brackets 56 in this instance have arms 75 projecting toward the fabric on which are mounted the shafts 76, carrying the detents 77 which are adapted to press the fabric against the shuttle tracks. The shafts 76 are provided with a lever 78 which in turn is fulcrumed to a link 79; and this link in turn is fulcrumed to a bellcrank lever 80, suitably mounted to operate the detents. The pitman 81 which is operated similar to the pitmen 60 and 68, from the shaft 54, is adjustably connected with the bellcrank lever 80, by means of the bolt and slot connection 82, 83, whereby the detent' device may be adjusted vertically in conjunction with the needle and other mechanisms.

. Mounting the various devices on the common bracket 56 makes the adjustment of the several sets of tools convenient.

In Fig. 11 the needle and detent mechanisms are shown on a large scale and the latter is shown with its parts connected in a somewhat different position.

It may be desirable to provide tension devices such as is shown in Fig. 12, for the purpose of doing away with the long tension roller 62. The two tension plates 84 press against the thread between them and the pressure is adjusted by meansY of the set nut 87, on the pin 86, regulating the pressure of the spring 85. These tension devices are suitably mounted by a bracket 88, one for each thread, whereby the space interyening between the several tensions is left ree.

In Figs. 15 and 16 I have shown, diagrammatically, several ways of arranging the needle bars, thread feed, tension and take up, for the purpose of preserving as open a view as possible of the embroidery surface. In Fig. 15, I have shown the take up bar 64, carried upon arms 65, which rock with the shaft 66, and the latter is mounted in front of the needle bar and in such a position that the takeup device as a whole will come in substantially the same plane as the needle bar. The support 61a, for the thread spool is arranged close to and underneath the needle bar 14. The tension roller 62 is here mounted between the spool support and take up. With the thread spools arranged close to and underneath the needle bar the stitching elements are more closely grouped than before and this enables me to arrange the various superimposed needle bars closer than heretofore and still permit the attendant to easily see between the parts and follow the operations of the many needles. The path of vision is indicated by arrows in Fig. 11. In Fig. 16, I also place the thread spool supports 61, immediately below the needle bar in order to give a clear view of the embroidering operations; but in this view I have sho-wn the tension roller 62, arranged just below the thread spools.

In Fig. 10 I have shown the shuttle tracks adjustable to correspond with the adjustability of the needle mechanisms. In the upper part of the View the tracks 17 are connected with the frame 53 by means of the bolts 89 engaging in slots 90 of the frame. The shuttle tracks are thus adjustiso able vertically, to bring them in proper relation with the needle mechanisms. The lower part of this view shows another method of adjusting the shuttle tracks. 1n this form the frame has an interrupted channel 91, in which the blocks 92 ot the shuttle tracks travel and a vertical shaft 93 is threaded through the blocks 92. By turning the shaft 93 the shuttle tracks may be vertically adjusted.

The present invention I believe to be broadly new and I do not wish to be limited to the exact forms and arrangements herein shown as the broad character of the invention may be followed in various other arrangements.

In using the terms vertical frame members and upright frame members l do not use them in a narrow sense but desire that they be given a meaning commensurate with the objects and scope ol my invention.
